We don't want this. It should still be a 'none' target (and that's fine).

This changes the semantics to actually produce a static lib, which should then
fail compiling due to ODR violations when 'policy' is built (also as a static
library)

[KushalP, 2012/01/13 12:47:50]

That makes sense. I got the impression that we wanted generated object files
because we'll only be including headers.

Doesn't this need to be '<(policy_out_dir)/policy' to match the
semantics/behaviours of the hand-rolled implementation?

The same for line 68.

These are generated files (by 'cloud_policy_code_generate'), so they don't exist
naked in the tree AFAICT.

Same here (re: none vs static_library)
